CURIOSITY LOW PIN COUNT DEVELOPMENT
BOARD USER’S GUIDE
Appendix B. General Notes
B.1 mikroBUS™ CLICKS
Module 1 is the main click socket, and Module 2 is the secondary socket. Both sockets
are fully compatible with a 40-pin PIC device; however, when using 28-pin devices, not
all pins are available.
All pins in Module 1 are available for use with the exception of the mikroBUS's Reset
(RST) signal, which is tied to pin RD0. PORT D is not available on 28-pin devices. If
the RST signal is needed, remove the solder blob jumper associated with the
mikroBUS RST connection, and place a jumper wire between the via next to the solder
blob jumper and the desired pin connection found in the J8 or J11 dual-row expansion
headers (see
Figure 1-1 ).
All pins in Module 2 are available for use with the exception of the mikroBUS's Reset
(RST) signal (RD2), SPI Chip Select (CS) signal (RD3), and the PWM (RD1) signal.
These signals are routed to the PORT D pins, which are not available on 28-pin PIC
devices. If these signals are needed, remove the solder blob jumpers associated with
the mikroBUS connection pins, and place jumper wires from the vias located next to
the associated solder blob jumpers to the desired pin connections found in the J8 or
J11 dual-row expansion headers (see
Figure 1-1 ).
B.2 SOLDER BLOB JUMPER
Solder blob jumpers can be found on each Click module, push-button switch, LED, or
potentiometer connection. This allows the user to utilize those pin connections for other
applications.
